CALF-WEANER.

SPECIFICATION forming part of Letters Patent N0. 349,104, datedSeptember 1%, 1886.

' Application filed March 10, 1886. Serial No. 194,738. (No model.)

To aZZ whom it may concern:

Be it known that I, HARVEY L. JONES, a citizen of the United States,residing at Coffeyville, in the county of Montgomery and State 5 ofKansas, have invented a new and useful Improvement in Calf-\Veaners, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in calf-weaners; and it consists ofthe peculiar and novel construction and combination of parts,substantially as hereinafter fully set forth, and specifically pointedout in the claims.

r The primary object of my invention is to provide an improved weaner,which can be easily and quickly adjusted upon the nose of a calf; toprovide a front shield, which can be adjusted vertically over the mouthof the calf or project outwardly therefrom at right angles; to provideside shields for clamping or bearing upon the sides of the calfsjaws,and to provide an improved weaning device that shall be simple anddurable in construction,

effective for the purposes designed, and cheap and inexpensive ofmanufacture.

In the accompanying drawings, Figure 1 is a perspective view of myimproved calf-weaner,

showing in dotted lines the front shield there- 0 of adjusted to anapproximately horizontal position. Fig. 2 is a plan view thereof. Fig. 3is a vertical sectional view on the line a; x of Fig. 2.

Referring to the drawings, in which like let- 3 5 ters of referenceindicate corresponding parts in all the figures, A B designate theclamps, which are made approximately U shape in form, one arm of eachclamp having an enlarged head or knob, c, at its outer end, that 0 isadapted to fit within the nostrils of the calf and bear against thecartilage that divides the nostrils. One end of the clamp A has anenlarged bearing, a, formed thereon, which is preferably madecylindrical in form; and this 5 bearing has a socket, a, which is squareor rectangular in cross-section, and has a transverse opening oraperture, a, in its inclosing- 'walls. The arm I) of the clamp B is madeof a shape and size corresponding to the shape and diameter of thesocket c, in which it fits very snugly to connect the clamps togetherwhen they have been/fitted to the calf s nose, and to prevent the clampsfrom becoming accidentally detached or separated from one another aspring key or pin. C, is passed through the aperture a and an opening,I),

in the squared end of the arm I).

D designates the front shield, which is preferably made of sheet metaland rectangular in form. The upper edge of the shield is hol- 6o lowedout or cut away, as at (Z, and to the curved edge is secured a' plate,E, which is also made of sheet metal and bent upon itself to provide acylindrical section or socket, e,

which fits loosely over and is free to turn or rotate on the bearing aof the clamp A. The ends of the plate are fitted on opposite sides ofthe shield and riveted thereto; or, if it is desired, the shield andsocket 6 may be cast in one piece. The cylindrical wall of the socket 0has a circumferential slot, 6, formed therein, which opens into thechamber of the socket, and through this slot the ends of the key or pinO project.

It will be observed that when the shield is in its vertical position thelower end of the key bears against the outer face of the shield, andthus prevents any forward movement of the shield; but when it is desiredto allow the animal to graze, the pin is withdrawn from engagement withthe shield, which is then turned forward, and the pin pushed through theaperture a to bear against the rear face of the shield, in whichposition the shield is free to rotate or turn on the bearing of theclamp, so that when the aniaml puts its nose to the ground the lowercurved edge, (1, of the shield will strike the ground and cause theshield to be moved upwardly out of the'way.

The clamps A B are provided with perforated lugs or studs f, to whichare loosely or pivotally connected eyes 9, formed on supporting-rods g,to which are secured the side shields, I, which are arranged in parallelplanes on opposite ends of the clamps, and adaptedto bear on the sidesof the jaws of the calf. The side shields are normally pressed towardeach other and against the jaws of the calf by a spring, H, which hasthe bent or angular arms h secured to the forward ends of I00 bear on,the jaws of the calf, to prevent accidental displacement of the deviceshould the animal attempt to detach it.

The operation of myinvcntion will be readily understood from theioregoingdescription, taken in connection with the accompanyingdrawings.

It will be observed that I provide a device for weaning calves which isvery simple and strong in its construction, thoroughly efl'ective forthe purposes, is comparatively cheap and inexpensive of manufacture, andreadily applied or detached and adjusted for use.

I do not desire to limit myself to the exact details 01' constructionand form and proportion of parts herein shown and described as anembodiment of my invention, as I am aware that many changes therein canbe made.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a calf-weaner, the combination of the clamps, a key passingthrough the connected ends thereof, and a front shield. having a tubularsocket, 0, provided with a slot, 6, lodsely fitted on the clamps, andhaving the ends of the key passed through the slot therein,substantially as described.

2. In a calf-weaner, the combination of the clamps, one having an openangular socket and the other an arm fitted snugly in the socket, a keypassing through the socket and arm, and a front shield carried by theclamps, substantially as described.

3. In a calf-weaner, the combination of the clamps having the lugs, theparallel side shields pivot-all y connected to the lugs at their forwardends, and a spring connecting the side shields at their pivoted ends,substantially as described.

4. The combination, with the detachable clamps, of the front shieldhaving a slotted socket or sleeve loosely journaled on the clamps, and apin passing through the clamps and the slot of the socket or sleeve,said pin being adapted to impinge against the front side of the shieldto prevent it from swinging outwardly, or to be adjusted to bear againstthe reverse or rear side of the shield, to adapt the shield to beelevated when the animal lowers its head to graze,substantiall y asdescribed.

5. The combination, with the clamps carrying a front shield adapted tobe attached to an animals nose, of the side shields pivoted to theclamps and arranged in rear of the latter and an arched springconnecting the side shields to normally force them toward each other,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
